In FIG. 1, there is shown an exploded perspective view of the overhead storage unit 10, herein after referred to as a storage unit 10. The storage unit 10 primarily includes a mounting frame 12, a swing means 14, storage bin 16 and an assist means 18. The mounting frame 12 is adapted to be secured or otherwise attached to the underside of a horizontal surface, such as ceiling or to rafters of a ceiling. The storage bin 16 is an open top type bin having a rear 20, a front 22, a first side wall 24, a second side wall 26, and a bottom 28. The swing means 14 couples the storage bin 16 to the mounting frame 12 and allows the storage bin to swing from a raised, stowed position as shown in FIG. 2 to a lowered and rearward position as shown in FIG. 3. The assist means 18 provides mechanical advantage to a user and allows the user to raise and lower the storage bin 16 in a controlled manner.

With reference to FIGS. 1-3, the mounting frame 12 includes a first and second side brackets 30 and 32, which are each attached to the mounting surface 34 parallel and approximate to the first and second side walls 24 and 26, respectively, of the storage bin 16. The first and second side brackets 30 and 32 each have a forward end 36 and a rearward end 38. The forward end of each being orientated towards the front 22 of the storage bin and the rearward end 38 of each being orientated towards the rear 20 of the storage bin. The first and second side brackets 30 and 32 can be of an L-shaped angle iron with the flange 40 of each being secured to the mounting surface 34 and the web 42 of each extending downward from the mounting surface.

The swing means 14 includes a first rear swing arm 44, a first rear swing arm 46, a first front swing arm 48, and a second front swing arm 50, each having opposite ends 52. The first rear swing arm 44 and the first rear swing arm 46 are each pivotally attached at one end to the storage bin 16 on the first and second side walls 24 and 26, respectively, at the rear 20 of the storage bin and pivotally attached at the other end to the mounting frame 12 to the first and second bracket 30 and 32, respectively, towards the rearward end 38 of each bracket. The first front swing arm 48 and the second front swing arm 50 are each pivotally attached at one end to the storage bin 16 on the first and second side wall 26 and 28, respectively, at the front 22 of the storage bin and pivotally attached at the other end to the mounting frame 12 to the first and second brackets 30 and 32, respectively, towards the forward end 36 of each bracket.

The first rear swing arm 44 and said first front swing arm 48 are each pivotally attached to the mounting frame 12 and the storage bin 16 such that they each lie in a common plane that is perpendicular to the front 22 and the rear 20 of the storage bin. The first rear swing arm 46 and the second front swing arm 50 are each pivotally attached to the mounting frame 12 and the storage bin 16 such that they each line in a common plane that is perpendicular to the front 22 and the rear 20 of the storage bin. The first and second rear swing arms 44 and 46 are parallel to each other and the first and second front swing arms 48 and 50 are parallel to each other.

With reference to FIG. 5 there is shown an exemplary pivotal coupling 54 of an end 52 of a swing arm with the storage bin 16. The pivotal coupling 54 is a bolted coupling including an elongated bushing 56 having a flanged head 58 which is inserted through a hole 60 through a side wall of the storage bin 16 until the flange head abuts the side wall. A bolt 62 is passed through a hole in the end 52 of the swing arm and through the bushing 56. A washer 64 is placed on the end of the bolt 62 followed by a nut 66. Again, this is just an example of a coupling that could be used to pivotally attach the end 52 of a swing arm to the storage bin 16 and various other couplings could reasonably be used.

With reference to FIG. 6 there is shown an exemplary pivotal coupling 68 of an end 52 of a swing arm with a bracket 30 or 32 of the mounting frame 12. The pivot coupling 68 is also a bolted coupling including a spacer bushing 70 which is positioned between the end 52 of the swing arm and the bracket. A bolt 72 is inserted through the end of the swing arm, the spacer bushing 70 and the bracket 30 and is secured with a nut 74. A washer is 76 positioned between the bolt head and the bracket 30 and between the nut 74 and the bracket as shown. Again, this is just an example of a coupling that could be used to pivotally attach the end 52 of a swing arm to the mounting frame 12 and various other couplings could reasonably be used.

With reference again to FIGS. 1-3, each swing arm further includes a bend 78 made at a point intermediate the opposite ends 52. The bend 78 being made in a plane parallel to the swing arm and in a direction towards the rear of the storage unit, as shown. The bend 78 allows the storage bin to swing from a raised, stowed position where an upper edge 80 of each first and second side walls 24 and 26 is substantially parallel to the horizontal surface 34, to which the storage unit 10 is mounted, to a lower and rearward position where the upper edge of each side wall remains substantially parallel to the horizontal surface.

With reference to FIGS. 1, 2, 3, and 9, in one version, the assist means 18 includes at least one coupling element 82, such as a tension spring, attached at one end to the mounting frame 12 and at the other end to either the swing means 14 or the storage bin 16. Preferably, in one version, the assist means 18 includes two tension springs 88, each having opposite ends 86 and two spring saddles 90. Each spring saddle includes a saddle portion 92 and a disc member 94 including a plurality of circumferentially spaced holes 96. A single spring saddle 90 is fixedly attached to each rear swing arm 44 and 46. One of the springs 88 is attached at one end to the spring saddle attached to the first rear swing arm at one of the spaced holes 96 and attached at the opposite end to the mounting frame 12 at the first bracket 30 at a position forward of the pivot coupling of the first rear swing arm with the first bracket. The second spring 88 is attached to the first rear swing arm 46 and the mounting frame 12 at the second bracket 32 in the same manner as the first spring is attached to the first rear swing arm 44 and mounting frame.

Each spring 88 is caused to at least partially wrap around the saddle portion 92 of its respective spring saddle 90 when the storage bin 16 is lifted into the raised, stowed position, thereby increasing the tension in each spring. The tension in each spring 88 acts on the swing means 14 to assist in lifting and lowering the storage bin 16. The tension in each spring 88 can be adjusted by attaching the end 86 of the spring to the spring saddle 90 at a different hole 96.

With reference now to FIGS. 4 and 8, in a second version, the assist means 18 includes a motor 98 having rotating shaft 100 and at least one flexible coupling element 102, such as strap connected at opposite ends to the mounting frame 12 and the rotating shaft. The motor 98 is attached to a rear end 104 of the storage bin 16. Preferably, the shaft 100 is double ended and attached to each end is a spool 106. A first coupling element 102 is attached at one end to a first spool with the other end of the coupling element attached to the mounting frame 12. A second coupling element 102 is attached at one end to the other spool 106 with the other end of the coupling element also attached to the mounting frame 12. The coupling elements 102, can be attached to the mounting frame 12 at a cross member 108 which spans between the first and second brackets 30 and 32 at a location forward of the pivotal coupling of the rear swing arms 44 and 46 with the mounting frame 12. The motor 98 is operated to wind and unwind each coupling element 102 onto and off of its respective spool 106, thereby effecting the lowering and raising of the storage bin 16. The motor 98 can be controlled by a switch 110 that operates to connect and disconnect the motor to a power supply 112.

Turn now to FIGS. 1 and 7, the latch means 114 includes a spring loaded latch 116 and a latch receiver 118. The spring loaded latch 116 includes a latch mounting bracket 119 for attaching the spring loaded latch to the horizontal surface 34 at a forward distance of the mounting frame 12. The latch receiver 118 is secured to the storage bin 16 at a front end 120 such that when the storage bin is raised and in the stowed position, the spring loaded latch 116 is captured by the latch receiver, thereby locking the storage bin in the raised, stowed position. The storage bin 16 is released from the spring loaded latch 116 by pulling upon a handle 122 which releases the spring loaded latch from the receiver 118, thereby allowing the storage bin 16 to swing from the raised, stowed position to the lower, rearward position.
